The common rule of thumb is that 10% of heifers born with a twin brother are fertile, leaving only 90% of heifers in a brother-sister twin combination sterile as freemartins or hermaphordites.

Can a heifer be a bull?
No. Heifers are female, bulls are male. Heifers cannot change their sex like some other creatures can. However, heifers that were born with a twin brother and shared the same placenta with her twin brother can develop bull-like characteristics. These are called Freemartins or Hermaphrodites. Hermaphrodites are 100% sterile, and a hermaphrodite heifer is a heifer that has both male and female sexual characteristics but can not fully become a bull like REAL bulls are.
How old does a bull calf have to be to get pregnant?
A bull calf is male with male reproductive organs, which means he cannot get pregnant. Only females (heifers, possibly heifer calves and cows) can get pregnant. Thus, your question has no merit whatsoever.
If a cow has twins can the twin get pregnant?
Only if the twin is a heifer and if that twin has been tested negative for being a freemartin (IF she had been twinned with a bull calf). Twin heifers are both highly likely to get pregnant when they reach puberty.
Are twin heifers sterile?
No. A heifer would only be sterile if she was twinned with a bull calf.
Is a heifer a pregnant cow?
No.
Does a heifer still mate when pregnant?
False heats are rare in cows or heifers that are already bred. If a heifer does go into heat when pregnant, it only occurs once or twice and that's it. But normally, no, a heifer won't still mate when she's pregnant.

No. A heifer would only be sterile if she was twinned with a bull calf.
Can a heifer be male?
Definitely not. Heifers are young female bovines, never male. The opposite of a heifer would be a young bull, which is a young male bovine.
Is a cow pregnant if its udders are full and all the other heifers udders are normal?
A cow is a mature female bovine that has had a calf. A heifer is a female bovine that has not had a calf. Therefore there are two possibilities: one, the cow you are referring to already had a calf and is still lactating, and she's in with the heifers (that are probably just weaned) to keep them calm. Two, yes she could be, but it's hard to say since you are referring to her as a cow and not a heifer.
Is a pregnant heifer a heifer or a cow?
It depends on you and what your plans are for the female and her calf and your experience with calving females. Often bred heifers are cheaper than bred cows, but they can be a pain in the rear when it comes down to calving, because they're predictably unpredictable. A bred cow will have more experience delivering and mothering up to a calf than a heifer will, and if you intend on keeping the calf for breeding (IF it's a heifer), then more often than not, if the cow's a good dam, the calf will be a good keeper. Not so for heifers: any calf that they birth should be raised for slaughter or sold, as they're not as good quality to keep for breeding purposes as her second, third, fourth, etc. calves will be. So it's all up to you.
Is a heifer a pregnant cow?
No.
What is the age limit of a bovine Heifer?
Most heifers should be around 15 to 18 months of age to be receptive and be able to get bred. Of course this depends on the breed and the type of cattle. For dairy cattle, a farmer aims to have a heifer calve by 24 months, or two years of age. The gestation period for a cow is approximately the same as for humans - nine months. Hence, a farmer usually aims to inseminate a heifer at 15 months of age, but this also depends on the health and condition of the animal and whether is is physically fit to become pregnant. For beef cattle, a heifer generally should be inseminated at around the same age. However, some breeds are quite late maturing, and will only be able to get bred at 18 to 22 months of age. Brahmans (or Zebu-type cattle) are late maturing, enough that only sees heifers getting bred or inseminated at this age.
